The French champions are keen to secure a summer move for the Blues forward while Atletico Madrid remain interested following a tumultuous campaign for the Spain international
Not only must Chelsea face Paris Saint-Germain in a vital Champions League clash, but the Blues must also fend off French attention for Diego Costa, according to the Daily Star.
Guus Hiddink's team hope to fight back from 2-1 down at Stamford Bridge to reach the quarter-finals at the expense of PSG.
But they will have to hope Costa's head is not turned by the attention, while Atletico Madrid are also reportedly interested in taking back their former striker.
